You've probably already decided, but I'll put in my $.02. If you want to print big( 20"x30"+), don't intend to shoot high volumes, or >ISO 400, then film offers great value. A 4x5 camera could be used to shoot 4x5, 6x12, 6x9, 6x7 etc. and give you movements with every lens. You could then pick up a V700, good for ~2500PPI, and get drum scans for anything in which you needed more. You can go
here to see full imacon scans of medium and large format. Almost all of those scans are <2500PPI except for the smaller formats. Drum scans would likely offer more resolution, better shadow detail, and less noise. I'd also consider the super sharp Mamiya 7(my next camera). It would require quite a bit more than 2500PPI to get everything off it's film, probably 2x that. I'm lusting for the 7's 43 or 50.
